TWINE-TENSION FOR BINDERS.

SPECIFlCATlON forming part of Letters Patent No. 690,186, dated December 31, 1901.

Application filed April 18, 1901. Serial No. 56,478. (No model.)

To a/ZZ whom rit may concern: ward of bearing-arm 7 reduced diametrically Be it known that I, FULTON D. RING, a citito form a screw-threaded portion 8, and jourzen of the United States, residing at Conway, naled upon said bolt is a corrugated roller 9, 55 in the county of McPherson and State of Kanthe forward end of said roller being tapered sas, have invented certain new and useful Imto conical or frustum shape, as at 10, this taprovements in Twine-Tensions for Binders, pered portion beingsmooth or non-corrugated. of which the following is a specification. 11 designates a conical nut which engages My invention relates to twine-tensions for the threaded portion 8 ot the bolt and se- 6o binders; and my object is to produce a device cures the latter and said roller reliably in polo of this character applicable to any of the apsition, and in this connection it will be noproved binders on the market with which the ticed that the taper of said nut corresponds twine may be more easily and quickly Seto the taper of the frustuin 10 and the intercured in or Withdrawn from engagement than posed enlargement or head 7b of bearing-arm 65 with the tension devices at present in use. 7, as shown clearly in Fig. 1.

(See Fig. 1.) This roller 12 is jourzo To these ends the invention consists in cernaled upon the cylindrical end 14 of a tentain novel and peculiar features of construcsion-plate 15, the latter being of spring metal, tion and combinations of parts, as hereinafter preferably, and formed at the front end of cydescribed and claimed, and in order that it lindrical portion 14E with a reduced threaded 75 may be fully understood reference is to behad portion 16, engaged by a nut 17, similar to to the accompanying drawings, in whichnut 11, and by reason of the greater length of Figure 1 represents a view principally in frustum 13 than of frustum 10 said nut occuside elevation of a twine-tension embodying pies a position vertically below nut 8. my invention, the same being shown as ap- Tension-plate 15 is formed at its rear end 8o plied to the bindingplatform of a harvestwithadepending forwardly-disposed hook 1S,

7i designates a longitudinallyextending the same being preferably in the form of rods bolt mounted in said bearing-arms and forbent spirally or convoluted attbeirlower ends to provide the guide-eyes 26 centrally between the rollers in order that the twine a, extending therethrough and between said rollers, shall extend in a straight line. Said rods eX- tend up through plate 2 and platform I and are engaged at their upper ends by retainingnuts 27, and in order to secure them more reliably in position they are convoluted to provide loops 28 to receive short bolts 29, the latter extending also through ears 4, nuts 30 e11- gaging the outer ends of said bolts to clamp said loops tightly up against the ears, as shown clearly.

In practice to secure the twine in operative position it is first threaded spirally in the guide-eyes 26 and then pulled in opposite directions through said eyes. This action moves the intermediate portion laterally in the direction indicated by arrow a into the flaring or V-shaped mouth formed by and between the tapered front ends of the rollers, nuts 1l and 17, and bearing-arm 7 and automatically between the corrugated portions of said roll'- ers, the lower roller yielding sufficiently to permit this object to be accomplished easily and quickly, and in this connection will be seen the reason why the head or enlargement 'b corresponds to the form and configuration of said roller and said nut. In such position the twine is fed in the usual manner, the lower roller yielding to pass all knots or irregularities without breaking or injuring the twine and without permitting the tension to rela-X, as will be readily understood.

The manipulation above described is reversed in removing the twine from between the rollers.

From the above description it will be apparent that I have produced what I term a selfthreading tension device for harvesting machines which embodies the features of advantage enumerated as desirable in the statement of invention, and while I have illustrated and described the preferred embodiment of the invention it is to be understood that it is susceptible ot' minor changes in the form, proportion, detail construction, and arrangement of the parts without departing from the spirit and scope or sacri ticing any of the advantages.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a tension device for binders, the combination of a pair of parallel tension-rollers, held together with a yielding pressure, and formed with non-corrugated tapering front ends to provide a V-shaped or Haring mouth,

and a pair of twine-guides, arranged at opposite sides of said rollers, substantially as described.

2. In a tension device for binders, the combination of a pair of parallel tension-rollers, held together with a yielding pressure, and having their front ends of non-corrugated tapering formv to provide a flaring mouth, and a pair of twine-guides at opposite sides of the rollers, and bent or convoluted at their lower ends to form eyes which receive and hold the twine between and in engagement with the rollers, substantially as described.

3. In a tension device for binders, the com bination of a pair of corrugated tension-rollers, held together with a yielding pressure, and having their front ends of non-corrugated and tapering form to provide a flaring mouth, and a pair of twine-guides at opposite sides ot' said rollers and bent or convoluted at their lower ends to form eyes which receive and hold the twine between and in engagement with the corrugated portions of the rollers, substantially as described.

4. In a tension device for binders, the combination of a plate secured to the binder-platform, a roller supported therefrom and having its front end of tapering formation, a tension-plate pivotally supported from the irstnamed plate, a roller journaled upon its front end, and tapered to correspond with the firstnamed roller, means for holding said rollers together with a yielding pressure, and twineguides at opposite sides of said rollers, substantially as described.

5. A tension device for binders, comprising a plate provided with a pair of bearing-arms, the foremost One having a. tapered head or enlargement, a bolt journaled in said bearing-arms, and provided with a threaded portion projecting forward of the arm having the head or enlargement, a roller journaled on said bolt, and having its front end tapered and bearing against the tapered head of said bearing-arm, a tapering or conical nut engaging the threaded end of said bolt and bearing against the opposite side of said bearing-arm, a tension-plate pivoted ,to the firstnamed plate, and guided to operate toward or from said roller, a companion roller journaled on said plate and provided with a tapered front end, a nut engaging the front end of said tension-plate and holding said roller thereon, a spring holding said plate pressed toward the first named roller, and twineguides depending from the first-named plate at opposite sides of said rollers, substantially as described.

In testimony whereof I afx my signature in the presence of two witnesses.
